A Sustainable Urban Mobility Plan (SUMP) is a planning concept applied by local and regional authorities for strategic mobility planning. It encourages a shift towards more sustainable transport modes and supports the integration and balanced development of all modes. A SUMP is instrumental in solving urban transport problems and reaching local and higher-level environmental, social, and economic objectives.

A Sustainable Urban Mobility Plan addresses all modes and forms of urban and regional transport. It aims to provide sustainable and high-quality transport and mobility in the agglomeration and enhance its accessibility. Instead of addressing the needs of the administrative area only, a SUMP regards the entire urban area including its commuter hinterland.[6][7] A SUMP integrates technical, infrastructure, policy, and soft measures to improve performance and cost-effectiveness. It aims to meet the basic mobility needs of all users. The SUMP concept emphasizes aspects of participatory planning, vertical and horizontal integration, and mechanisms for monitoring, evaluation and quality control.[8]
